Quantitative Static and Dynamic Assessment of Balance Control in Stroke Patients

Summary

Presented here is a quantitative, clinical balance assessment method suitable for stroke patients with balance disorders.

Abstract

In patients with stroke, damage to the central nervous system (CNS) can affect the postural stability and increase the risk of falling. Therefore, accurately assessing the balance is important to understand the type, extent, and causes of balance deficit, and to identify individualized interventions. Clinical assessment methods for balance function can be broadly divided into observation, scale assessment, and balance instrument testing. Here, a clinical protocol is presented for static and dynamic balance assessment in stroke patients, which includes three semiquantitative balance function scale assessments (i.e., Berg Balance Scale, Timed Up and Go Test, and Fugl-Meyer Assessment) and three quantitative instrumental balance evaluation (i.e., Stability Assessment Module, Proprioceptive Assessment Module, and Limit of Stability Module). It is recommended that clinicians consider the use of both classic clinical balance scales and instrumental balance measurements when assessing stroke patients to improve the accuracy of assessments, leading to a better individualized treatment plan.

Introduction

The human body can maintain posture stability under various conditions, including internal and external disturbances¹. Balance relies on sensory input, integration of the central nervous system (CNS), and motor control². In patients with stroke, damage to the CNS can affect the ability to maintain balance³. Postural instability is an important risk factor for falls⁴. Approximately 70% of patients experience a fall in the first year after stroke, often with serious consequences, such as hip fracture in elderly patients^5,6<....

Protocol

The clinical project was approved by the Medical Ethics Association of the Fifth Affiliated Hospital of Guangzhou Medical University and has been registered at the China Clinical Trial Registration Center (No. ChiCTR1900021291) with the title “The mechanism and effect of Pro-kin system training on static and dynamic balance”.

Discussion

Described is a clinical protocol for static and dynamic balance assessment in stroke patients that includes three semiquantitative balance function scale assessments (BBS, TUG, and FMA-LE) and three models of quantitative instrumental balance evaluation (Stability Assessment, Proprioceptive Assessment, and Limit of Stability). The design of this protocol was based on five main points.

First, the BBS is a 14-function-task on a 5-point scale that semiquantitatively assesses static and dynamic ba.......
